Hi Edward, a beauty indeed, although to a non car person I don't really understand why it has a hole in it? Anyway - on to the photo itself.... ;)
A colourful image with well controlled highlights and shadows and good focus.
After some consideration
Two of your commenters rightly mentioned the composition of your image. About a third of the image is taken up with tarmac, try some different crops to see how it works with less of it. The trouble will probably be that a crop like that will leave you with a long, not so high image that might not be that pleasing. Did you have a chance to get up close to the car, and did you have your 17-40mm lens with you? Lying on the ground with a 17mm lens with that lovely blue sky could get you some other cracking shots.
Still on composition, the car is 'looking' away from us which makes it seem a little unfriendly, you may have had limited access but including one or both head (or rear) lights gives you more of a 'face' to engage with. (It could well be that you captured the best view of this vehicle for a car lover, I'm just commenting as someone who isn't that into cars ;) )
Enough 'criticism', there's plenty that's good here, you've got a good focus, some great colours and you've used your post processing to tackle what I imagine was quite a contrasty image to give a nicely controlled balance, as I mentioned earlier.
A well executed image only let down by the composition.
Thank you for allowing me to spend more time with a car image than I normally would, maybe you could explain that hole to me :)
